  • Publication number: 20130044419
    Abstract: An electronic part is held in a sheet-metal part holder having a U-shaped cross-section. The part holder holds the electronic part between a first face and a second face thereof. A front casing corresponding to the first face and a rear casing corresponding to the second face each have an opening bored such that the first face or the second face is exposed through the opening. This enables the thicknesses of the casings to be reduced to that of the part holder.

  • Patent number: 7081063
    Abstract: An internal planetary gear mechanism reduces a load applied to tooth surfaces of an external gear and an internal gear, a sliding portion such as a bearing and the like. By setting the amount of eccentricity ? of an eccentric part to be larger than a theoretical value, a distance between the center of the external gear and the center of the internal gear is increased to allow the reduction of a loss in the bearing and on the tooth surfaces of the gears, and a mesh zone between the internal gear and the external gear can be reduced to decrease a part at a large pressure angle, thereby reducing a loss generated by a large pressure angle. As a result of reduction in the mesh zone between the external gear and the internal gear, rolling contact of the gears is maintained.

  • Patent number: 6378840
    Abstract: In an electromagnetic valve, a seat member has a protruding portion having two parallel surfaces provided in the seat member. When the seat member is fixed to the base member by inserting molding, the two parallel surfaces of the protruding portion may be put between projecting portions of a pin of a molding die. As a result, the fluid passage of the seat member may be easily positioned to correspond to an opening of the base member. Further, after molding, the seat member may be prevented from rotating in the base member since the parallel surfaces are partly covered by resin of the base member.

  • Patent number: 5893534
    Abstract: The problem solved by this invention is to eliminate an oil can movement of the web of an aircraft pressurized bulkhead. A hat section support stiffener is attached to the web by an adhesive. Two end brackets are attached by Hi-Loc bolts to bulkhead stiffeners and the end brackets are attached and arranged to provide a downward pressure on the hat section stiffener to assist in holding it in place. This invention is characterized by the absence of any new fasteners passing through the fatigue critical bulkhead web and also is characterized by the absence of any requirement for removal of existing fasteners, including, but not limited to those passing through the bulkhead web.
